7.2 Systems and Components
There are many systems and components on the DC side
of your boat from emergency and safety to entertainment.
These systems make up the largest part of your electrical
system.
Here we will discuss the electrical parts of those systems
and try and give you a better understanding of the uses
and features of your DC electrical systems and compo-
nents. Since the largest part of your controls are at the
MDP, we will start there and run down the systems and
components as they are listed on the MDP. From there,
we will look at the battery switch panel, and finally, the
helm controls.
7.2.1 DC Main
In order to energize the DC system aboard your boat, you
must turn the breaker marked “DC Main”, on the battery
switch panel, to the “On” position. This supplies power to
the remaining breakers and systems on the distribution
panel.
7.2.2 Water Systems
The water systems are outlined in the Water Systems
chapter in this manual. However, the controls and
p
monitors for these systems are all powered by the DC
Electrical system.
The water tank monitor as shown in Fig. 7.4 allows you
to select the tank to monitor the water level in the respec-
tive tank.
The power switch turns the monitor on, then
select the tank you want to monitor. The gauge on
the left will show the amount remaining in the tank.
The waste tanks are also monitored from this location by
selecting numbers six, or seven from selector switch #1
on Fig. 7.4.
7.2.3 Refrigerator
The breaker marked “refrigerator”, on the main breaker
panel behind the starboard salon seat, supplies power
to the DC powered refrigerator aboard your boat. See
Fig. 7.5 for the arrangement layout of this system.
